Abstract
The rapid growth in the Internet of Things (IoT) leads currently to an increase in the density of the number of connected objects typically in free bands. Operating in unlicensed bands requires connected objects to reduce their energy consumption. To that end, one of the adopted techniques is the random access to the radio channel. The main downside of uncontrolled medium access is almost always the high interference level inherent to both self- as well as cross-technologies. Among the various technologies that are used to connect this massive number of devices, we distinguish two emerging technologies based on spread spectrum and ultra narrow band. The goal of this paper is to analyze the impact of the coexistence of these two technologies, in Industrial, Scientific, and Medical (ISM) unlicensed bands, in terms of bit error rate by defining a formal expression for the interfering signals.
